Are you in the market for an insulation system that is easy to install in an interior basement? Quik-Therm utilizes proprietary technology created by Winnipeg renovation expert, Ted Cullen. Our Interior Basement and Concrete Insulation System (CIS) uses high-density foam studs that interlock with polystyrene panels to form a solid wall. This two to three-inch thick wall acts as an air, vapour, radon, and radiant barrier all in one.
